|Title:||Co-sputtered Carbon-nickel Nanocomposite Thin Films|
|Abstract:||Carbon-nickel nanocomposite thin films were prepared by co-sputtering a graphite target with a small Ni chip attached on its surface. The Ni concentration in the films was controlled by the size of the Ni chip and measured by in-situ X-ray photoelectron spectroscopy. Transmission electron microscopy images showed that the films have a granular structure with nanosized Ni particles embedded in an amorphous carbon matrix. The Ni particles have an average diameter of ∼4 nm, with a rather narrow size distribution. Magnetization measurements revealed that films are superparamagnetic and present blocking temperatures TB < 15 K.|
